Kids steal the show at ministry ceremony

Babies wait for no one, not even the swearing in of Malcolm Turnbull's frontbench.

Governor-General Peter Cosgrove had to raise his voice to compete with the squealing and giggles of little ones as he swore-in the prime minister's new-look ministry in Canberra.

"It's baby central," Kelly O'Dwyer cried as she arrived for Tuesday's ceremony, walking up the driveway of Government House with 14-month-old daughter Olivia in her arms, just as cabinet colleague Christian Porter emerged from his car carrying son Lachlan.

The newest member of cabinet, Matt Canavan, arrived with his four young sons wearing matching blue shirts, while Justice Minister Michael Keenan was also accompanied by his young family.

"Are you excited?" he asked sons William and Theo, who replied "yes" with beaming smiles.

One by one, Mr Turnbull's ministers rose with bibles in hand to make their pledges.

Michaelia Cash received a "hear hear" as she stood to take her oath, celebrating her birthday as well as her swearing-in.
